What is the difference between json.dumps and json.load?
From my understanding, one loads JSON into a dictionary and another loads into objects.

dumps takes an object and produces a string:
>>> a = {'foo': 3} >>> json.dumps(a) '{"foo": 3}' load would take a file-like object, read the data from that object, and use that string to create an object:
with open('file.json') as fh: a = json.load(fh) Note that dump and load convert between files and objects, while dumps and loads convert between strings and objects. You can think of the s-less functions as wrappers around the s functions:
def dump(obj, fh): fh.write(dumps(obj)) def load(fh): return loads(fh.read()) json loads -> returns an object from a string representing a json object.
json dumps -> returns a string representing a json object from an object.
load and dump -> read/write from/to file instead of string
